Kutaya njira yoponyera thovu

Mfundo yopangira LFC, Choyamba, mitundu yoyera ya thovu imapangidwa motsatira zofunikira za kapangidwe ka chinthucho. Chachiwiri, ikaviikidwa ndi chophimba chosasunthika ndikuwumitsa, mitunduyo imayikidwa m'mabokosi amchenga opangidwa mwapadera okhala ndi mchenga wouma kuti ipange mawonekedwe olimba amitundu itatu ndi kuthira madzi osungunuka pansi pa vacuum state, Kenako mitunduyo imapita chifukwa cha mpweya ndi madzi osungunuka omwe asinthidwa, motero, ma castings oyenerera amapangidwa.

Malo oyera a LFC amagwiritsidwa ntchito popanga mitundu yoyera ya thovu kudzera mu pre-thomu, kucha, kupanga, kudula ndi kulumikizana. Zipangizo zopangira zimaphatikizapo EPS, STMMA, EPMMA ndi zipangizo zina zokulitsa thovu.

Mwachitsanzo, mikanda ya EPS yomwe imagwiritsidwa ntchito kwambiri, makhalidwe a mikanda ya EPS: semitransparent, preforming rate: 40 ~ 60 times, mikanda m'mimba mwake: 0.18 mpaka 0.80 millimeters, makulidwe 6 osiyanasiyana, nthawi zambiri, m'mimba mwake wa mikanda yoyambirira iyenera kukhala yochepera, 1/9 ~ 1/10. kapena yofanana ndi 1/9 mpaka 1/10 ya makulidwe ochepa a khoma la castings. Kupanga thovu pogwiritsa ntchito zinthu zopangira kutsata kusankha mikanda yoyenera, thovu lisanapangidwe.

Kupaka thovu

Musanalowetsedwe mu nkhungu, mikanda ya EPS iyenera kukulitsidwa mpaka kukula kwinakwake. Njira yopangira thovu imatsimikizira kuchuluka, kulondola kwa kukula kwake, komanso kukhazikika kwa mitunduyo. Pali mitundu iwiri ya zida zopangira thovu la EPS: makina amagetsi opangira thovu, ndi makina oyera opangira thovu, onse awiri ali ndi ukadaulo wapamwamba kwambiri wa PLC.

Kukhwima

Mikanda ya EPS yopangidwa kale ndi thovu imayikidwa, mu silo youma komanso yopumira mpweya kwa nthawi inayake, zomwe zimapangitsa kuti mkati ndi kunja kwa mikanda ikhale yolimba, imawonjezera kusinthasintha ndi kukula, ndikuchotsa madzi pamwamba pa mikanda. Kenako imatumizidwa ku hopper yosungiramo zinthu kudzera mu njira yodyetsera yokha.

Kupanga zitsanzo za thovu

Pambuyo pokonza, mikanda ya EPS imalowetsedwa m'chibowo cha thovu chotayika pogwiritsa ntchito makina opondereza ndikutenthedwa, kuti mikandayo ikulitsidwenso ndikusakanikirana pamodzi, kudzaza chibowo ndikupanga malo osalala. Ma Model ayenera kuziziritsidwa ndikukhazikika asanayambe kukonzedwa. Pambuyo pokonza, payenera kukhala nthawi yokwanira kuti ma Model aume ndikukhazikika, Mtundu woyera umakhala wonyowa pamwamba, ndipo uli ndi chinyezi mkati, kotero uyenera kuumitsidwa bwino.

Pali mitundu iwiri ya zida zopangira: makina opangira ma hydraulic ndi makina opangira ma screw. Chomera cha thovu chotayika chimapangidwa ndi aluminiyamu, ndipo chimapangidwa molingana ndi kapangidwe ka zinthu zosiyanasiyana, kudula ndi kulumikiza ma model, Zogulitsa zopangira ma modeli zitha kukhala gawo la model kapena ma form blanks oyamba, omwe amafunika kukonzedwanso kwina monga kudula ndi kulumikiza, Njira iyi ndikuphatikiza mitundu yambiri ya thovu loyera ndi gating, ndi mitundu yokwezera ndi guluu wapadera wa thovu wotayika kuti apange magulu a model.

Malo achikasu a LFC

Amagwiritsidwa ntchito makamaka popukuta utoto wapadera pa magulu oyera a zitsanzo ndi kuumitsa m'zipinda zoumitsira, Ntchito zazikulu za utoto mu LFC ndikuteteza madzi achitsulo ndi chitsanzo, kutulutsa mpweya woipa wa chitsanzo, kuonetsetsa kuti pamwamba pake pali mtundu wa zinthu zotayidwa, kulimbitsa mphamvu ndi kuuma kwa zitsanzo ndikuletsa kuwonongeka kapena kusinthika kwa zitsanzozo pamlingo winawake.

Izi zimafuna kuti chophimbacho chikhale cholimba komanso chosapsa ndi moto kuti chichepetse zolakwika pa zinthu monga ma blowhole, kuyaka mchenga kuti zitsimikizire kuchuluka kwa zinthu zomwe zamalizidwa, nthawi zambiri pali njira zinayi zophikira ndi kupachika: kutsuka, kuviika, kuwaza, ndi kupopera.

Malinga ndi makhalidwe a mitundu yosiyanasiyana, njira zingapo zingagwiritsidwe ntchito mokwanira popanga zinthu zenizeni. Pambuyo popaka utoto, mitundu imasunthidwa ku zipinda zouma zokhala ndi kutentha kwa 45 ~ 55℃, zomwe zimazungulira mpweya wotentha kuti ziume, Panthawi youma, mitundu iyenera kuyikidwa moyenera komanso mothandizidwa kuti isasinthe mawonekedwe, Pakadali pano, kutentha ndi chinyezi ziyenera kulamulidwa mosamala kuti ziume bwino, Pambuyo pouma bwino, magulu amitundu amakhala okonzeka kuthiridwa.

Njira yakuda ndi gawo la kuponyera kolimba, Magulu ouma amaikidwa m'mabokosi amchenga, Mchenga wouma wapadera umaperekedwa ku bokosi la mchenga ndi makina osunthika odyetsera shawa kuti awumbe, Madzi osungunuka amathiridwa pansi pa kupanikizika koipa, Mamodeli osungunuka ndi madzi osungunuka m'malo mwake, Mamodeli osungunuka ndi madzi osungunuka m'malo mwake, Chifukwa chake, ma castings oyenerera amapangidwa.

Malo akuda a njira yotayira thovu ndikusintha mitundu yoyera ya thovu ndi chitsulo chosungunuka ndikuyika mawonekedwe, Pali magawo atatu: kugwedera kwa kuumba, kuyika m'malo mwa kuyika ndi kuchiza mchenga.

Malo opangira zinthu zomangira amagwiritsa ntchito nsanja yogwedera pamodzi ndi makina odyetsera mchenga wosambira kuti azipangira zinthu, mabokosi a mchenga amasamutsidwa kupita pamalo omwe ali pansi pa mchenga. Chotsukira cha mvula chimawonjezera mchenga pansi pa bokosi la mchenga, mchenga wapansi ukawonjezedwa, gulu lachitsanzo limayikidwa mu bokosi la mchenga, ndipo chotsukira cha mvula chimayikidwanso kuti chiwonjezere mchenga pamalo otsetsereka. Pa nthawi yonse yodzaza mchenga, tebulo logwedera limagwedezeka kuti litsimikizire kuti likupangidwa, mchenga umadzazidwa mpaka malo opanda kanthu mozungulira gulu lachitsanzo la thovu. Pambuyo pogwedeza, kuwonjezera mchenga pamwamba ndikuphimba mapepala apulasitiki, kumaliza kupanga zinthu.

Tsitsani tebulo logwedezeka, ikani bokosi la mchenga panjira, ndipo gwiritsani ntchito makina opukutira bokosi la hydraulic kuti mukankhire bokosi la mchenga kutali ndi malo opangira zinthu pansi pa chosungira mchenga kuti mupange bokosi lotsatira.

Pambuyo poumba, mabokosi a mchenga amasamutsidwira ku gawo lothira limodzi ndi limodzi, Gawoli lili ndi makina olumikizira matako odziyimira okha omwe amathira mphamvu, akathira, chitsanzo cha EPS chimatenthedwa ndi kutentha kwa chitsulo chamadzimadzi, mpweya wopangidwa ndi mpweya umalowa mu dongosolo lopanikizika loipa kudzera mumchenga wopaka ndi woumba. Chitsulo chamadzimadzi chimakhala pamalo a chitsanzo cha EPS ndipo chimachitika njira yosinthira chitsulo chamadzimadzi ndi chitsanzo cha EPS. Pomaliza, ma castings oyenerera amapangidwa.

Pambuyo pothira, zotayira ziyenera kuziziritsidwa kwa kanthawi mu sandbox, kenako nkutembenuzidwira kunja kwa bokosi. Makina osinthira okha amagwiritsidwa ntchito kusiyanitsa zotayira ndi mchenga, mchenga woumba umapita ku dongosolo lothandizira mchenga, pomwe makina oponyera mfuti amachotsedwa pamwamba.

Dongosolo lothandizira mchenga ndi njira yofunika kwambiri yopangira LFC, Kuumba mchenga pambuyo pa bokosi kumaziziritsidwa makamaka ndi makina oziziritsira mchenga m'madzi, Kenako kumalekanitsidwa ndi zotsalira zamadzi ndi zinthu zina pogwiritsa ntchito makina oyeretsera, chotengera cha screeninq chili ndi makina oziziritsira mpweya, omwe amatha kuchepetsa kutentha kwa mchenga mwachangu komanso moyenera, zotsalirazo zimachotsedwa ndi makina okweza slag pomwe chopangira, mchenga umakwezedwa ndi elevator kupita ku chowongolera kutentha cha mchenga kuti chiziziritsidwe kwambiri, Pambuyo pa zonsezi, mchenga umasamutsidwira ku storaqe hopper kuti upangidwe.

Dongosolo lonse lokonza mchenga limagwiritsa ntchito njira yapamwamba yowongolera PLC. Ntchito yonseyi ili ndi njira yowongolera kutentha kwa mchenga, kutentha kokha komanso kusintha pafupipafupi, ndipo pamapeto pake imamaliza kuyeretsa, kuchotsa fumbi ndi kuziziritsa mchenga woumba, zomwe zimathandiza kuti mchenga woumba ubwererenso.

Mu dongosolo lonse lochizira mchenga, node iliyonse imagwiritsa ntchito chosonkhanitsira fumbi, chomwe chimagwiritsidwa ntchito kwambiri mu dongosolo lochotsa fumbi, ndi chochotsa fumbi chamtundu wa pulse bag, chomwe chimagwira ntchito makamaka pochiza fumbi la node iliyonse mu dongosolo lochizira mchenga la LFC. Kampani ya GuoNing yapanganso njira yochizira mpweya wotulutsa utsi, yomwe imagwiritsidwa ntchito makamaka kuyeretsa mpweya wa benzene wopangidwa, pogwiritsa ntchito mpweya woyera wopangidwa panthawi yothira, imagwiritsa ntchito kukhetsa kwa adsorption desorption catalytic ndi zina zotero kuti itsuke mpweya wotulutsa utsi, kukwaniritsa zofunikira pakupanga ndi chilengedwe, komanso kupanga bwino.
